Object Oriented model:An object has values stored in instance variables within the object. An object also has bodies of code that execute on the object. These bodies of code are named methods. Objects that have same kinds of values and the same functions are grouped together into classes. The object-oriented paradigm gives the programmer to address the complexity of a problem domain by obtaining the problem not as a set of methods that can be operated but primarily as a set of interacting, related Objects. The modeling task then is specifying, for a specific context, those Objects, their respective group of Methods and Properties, shared by all Objects group members of the Class.
